2. Safety Guidelines
Your safety is paramount. Adhere to all safety instructions to prevent injury or damage to the wheelchair.
- EABS Parking System: The Electronic Automatic Braking System (EABS) engages automatically when the joystick is released, providing immediate stopping power. This system also features slope-sensing technology, which automatically stops the wheelchair on inclines up to 12 degrees when the joystick is not engaged.
- Anti-Tip Wheels: Equipped with rear anti-tip wheels to enhance stability and prevent backward tipping, especially on inclines or uneven surfaces.
- Seat Belt: Always use the integrated seat belt for secure seating during operation. The seat belt features a quick-release buckle for easy fastening and unfastening.
- Weight Capacity: Do not exceed the maximum weight capacity of 330 lbs (150 kg).
- Environmental Conditions: Avoid operating the wheelchair in extreme weather conditions, such as heavy rain or snow, to prevent damage to electronic components.
